Before the construction of the roofing project, the construction unit should organize technical management personnel to review the roofing project drawings, master the construction drawings of the detailed structure and the relevant technical requirements and the actual situation of the project to prepare the construction plan or technical measures of the roofing project. This avoids construction defects left behind, resulting in rework, while the project is based on the construction organization to start construction in a planned manner to prevent work omissions, mistakes, upside down affect the quality of the project. Waterproofing coating manufacturers to introduce in detail.
Roofing membrane waterproofing construction before the following points to do a good job
A, waterproof coating manufacturer that the technical preparation before construction
Before the construction of roofing projects, the construction unit should organize technical management personnel to review the roofing project drawings, grasp the construction drawings in the details of the structure and technical requirements and according to the actual situation of the project to prepare the construction program or technical measures for roofing projects. This avoids leaving defects after construction, resulting in rework, while the project is planned according to the construction organization to prevent work omissions, mistakes, reversals affect the quality of the project.
With the construction organization, the next step of construction should be responsible for the technical delivery to the team. Content includes: construction parts, construction sequence, construction process, construction level, node set up methods, enhance parts and practices, engineering quality standards, technical measures to ensure quality, finished product protection measures and safety precautions.
Second, waterproof coating manufacturer that the requirements of the construction personnel and construction procedures
Waterproofing of roofing projects must be waterproofing professional team or waterproofing construction, is strictly prohibited without the qualification level certificate of the unit and non-waterproofing professional team or non-waterproofing workers for waterproofing construction of roofing projects, construction units or supervisory companies should carefully check the induction certificate of construction personnel. Construction units should be construction processes, levels of quality self-inspection, self-inspection, self-correction and good construction records, supervision units do a good job of acceptance of each step process, acceptance before the next process, level of operation.
Third, the waterproof coating manufacturer that the quality requirements of waterproofing materials
Waterproofing materials used in roofing projects should have material quality certification documents, and certified by the designated quality testing department to ensure that its quality in line with the "technical specifications for roofing projects" (GB50207-94) or the requirements of the relevant national standards. Waterproofing materials into the construction site should be accompanied by factory inspection reports and factory certificate, and indicate the date of production, batch number, specifications, name. The construction unit shall be required to take samples for review, sample review in strict accordance with the witness sampling system, in the construction unit representative or supervisory unit personnel witnessed by the construction personnel in the field sampling, sent to the laboratory for testing. After passing the re-inspection, submit a re-inspection test report before application in waterproofing projects. Prohibit the use of unqualified waterproofing materials in the project, unqualified materials should be found immediately all withdraw from the construction site.
